摘　　要：利用微波等离子体炬原子发射光谱法 (MPT-AES) ,通过在线分离富集测定 Cd,Cu和Zn.考察用 MPT-AES测定这些元素的条件及共存物的影响 .Cd,Cu和 Zn的检出限分别为4.0 ng/ m L,3 .0 ng/ m L和 4.0 ng/ m L,并用于实际样品分析 ,得到满意的结果 .Cd, Cu and Zn were determined by on line preconcmtration microwave plasma torch atomic emission spectrometry. The experimental conditions and the effects of some coexistent elements were examined. The detection limits for Cd, Cu and Zn were 4.0 ng/mL, 3.0 ng/mL and 4.0 ng/mL, respectively. The method was applied to the analyses of some samples with satisfactory results.
